The Cohesion3D Mini can be dropped into the K40 Laser Cutter in under 20 minutes to provide an immediate performance upgrade. Smoothie is the only firmware which calculates the PWM value based on acceleration every single step, resulting in the cleanest possible cut and even power around corners. No burned corners here!
The K40 is a very inexpensive laser cutter that can be procured on eBay in the $340 range. It is capable of engraving leather and metal and cutting wood and plastic. However, the stock electronics are very lacking in functionality and actually restrict the user to a limited version of Coreldraw which is not pleasant to use. This upgrade opens the door to using any gCode generator and sender to control your machine, such as the awesome Lightburn Software.
We highly recommend adding our USB Cable and power supply upgrade kit to your order. The USB Cable that comes with the K40 is known to cause communications issues, and the power supply in the K40 puts out a very weak 24v rail that can cause stability issues. If you want to add a Z Table and/or Rotary attachment to your K40, you must absolutely use a separate power supply for the board.
